Dark Rock 5 210 W air cooler

The Dark Rock 5 is a 120 mm tower cooler rated for 210 W TDP. Six copper heat pipes and a black ceramic-coated aluminium fin stack transfer heat to a Silent Wings 4 PWM fan. It fits Intel LGA 1700, 1851, 1200, 1150, 1151, 1155 and AMD AM4, AM5 sockets. The 161 mm height suits most mid-tower cases.

Pre-fitted bridge eases mounting

A pre-installed mounting bridge and captive screws let you secure the cooler without loose parts. The asymmetrical fin cut-outs clear tall RAM modules and VRM heatsinks on most boards. The only common snag is the 120 x 120 x 25 mm fan overhanging the first memory slot on some compact layouts, which a second optional fan would worsen.

29.8 dBA at 2100 RPM sustained

At full 2100 RPM the fan delivers 55 CFM and 2.73 mm H₂O static pressure while peaking at 29.8 dBA. The fluid-dynamic bearing and rubberised frame keep vibration low during long renders or compiles. Thermal mass of the 1013 g heatsink absorbs short spikes, so temperatures rise gradually rather than spiking under continuous load.

Questions about this item

How do I confirm the cooler is performing correctly after installation?

Monitor CPU temperatures under load; the cooler is rated for 210W TDP with a maximum noise level of 29.8 dBA at 2100 RPM, so temperatures should stay within safe limits while the fan remains quiet.

What accessories are included and what must I purchase separately?

The box contains thermal grease, a screwdriver, and a complete mounting set for Intel LGA 1700/1851/1200/1150/1151/1155 and AMD AM4/AM5 sockets; no extra parts are required for standard installation.

Which version should I choose for my case and memory setup?

The single 120mm Silent Wings 4 model fits cases with 161mm CPU cooler clearance and its asymmetrical heatsink with cut-outs provides unlimited RAM height compatibility.
